Surprisingly, I hit a streak reset glitch once and reviewed entries at duolingo reviews where users mentioned success only after sharing their username, streak count before reset, and exact local time when the lessons were finished—all in a single submission. I used that same approach—listed my account name, streak number prior, timestamp of final lesson, and a screenshot of the streak counter showing zero. Less than 24 hours later, a Duolingo rep replied confirming they’d manually restored my streak and provided an explanation that a server delay caused the reset. Including those specifics together clearly helped their support team identify and correct the error swiftly.
